Step 1

Take a plate and screw 4 big spacers underneath at the indicated places. This plate will be the central plate of the esieabot.

Warning

Pay attention to the orientation of the plate. The logo can help you to orientate yourself.

Step 2

On the same plate, screw 2 large spacers on the top at the indicated locations.

Step 3

Take the two motors and screw in the metal motor supports with the large screws.

Warning

Attention, the placement of the supports has a direction to respect. There is a small deception in the form of a yellow cylinder on the motors. The metal bracket must be installed on the other side.

Step 4

Position the motors on the central plate at the indicated locations. They will be fixed permanently afterwards.

Step 5

Take a new plate and screw the freewheel to the indicated place with the small screws. Then position and screw this new plate on the old one at the indicated place. The motors should now be fixed.

Step 6

Place the battery between the 2 motors. It must be able to hold by simple friction. If necessary, you can use a scratch.

Step 7

Take 2 male/female scratch pads and place them under the battery holder. Then glue the battery holder to the center plate where indicated.

Warning

You cannot charge your batteries while they are in the battery holder. You must absolutely remove them.

Step 8

Screw the small spacers on the Raspberry Pi at the indicated places.

Note

If your screws are too small, you can use plastic washers to adjust.

Step 9

Take a new plate and screw the Raspberry Pi to the indicated place.

Step 10

On this new plate, stick the breadboard in the indicated place. Then screw the plate on the rest of the esieabot.

Step 11

If your H-bridge is not already in your breadboard, you can install it now, with the key on top of the image.

Step 12

Screw the wheels with their tires on the indicated places.

Step 13

Connect the wires between the motors, the Raspberry Pi and the breadboard as shown.

Warning

Do not connect the batteries until you have checked that the rest of the connection is correct. You could destroy components otherwise.

Note

On the breadboard, the columns are connected to each other except in the middle where they are cut. So the location of the wires does not matter, as long as they are on the right column. Similarly, the color of the wires is not important. However, it is advisable to respect it in order to be able to diagnose potential problems with the support more quickly.

Step 14

Congratulations, your esieabot is now assembled. Now you have to install its operating system to give it life. To do this, go to the Using an esieabot section. If you have a camera turret, you can also assemble it.
